INTERNAL COMBUSTION ENGINE WITH REDUCED OIL MAINTENANCE - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240011452 titled 'INTERNAL COMBUSTION ENGINE WITH REDUCED OIL MAINTENANCE

Simplified Explanation

The abstract describes an internal combustion engine that includes an engine block, a piston, and a cylinder head. The engine block consists of a cylinder block with a cylinder bore, a crankcase defining a crankcase chamber with a crankshaft positioned inside, and a cylinder sleeve made of a self-lubricating plastic material. The cylinder head is connected to the cylinder block to form a combustion chamber. The piston has a piston top near the combustion chamber, a piston body with a wrist pin hole to receive a wrist pin, a first piston ring, and a non-metallic gasket positioned closer to the combustion chamber than the first piston ring to prevent combustion gases from escaping. The crankcase chamber operates without the need for oil.

  • The internal combustion engine has an engine block, piston, and cylinder head.
  • The engine block consists of a cylinder block, crankcase, and cylinder sleeve.
  • The cylinder block has a cylinder bore, and the crankcase defines a crankcase chamber with a crankshaft inside.
  • The cylinder sleeve is made of a self-lubricating plastic material.
  • The cylinder head is connected to the cylinder block to form a combustion chamber.
  • The piston has a piston top, piston body with a wrist pin hole, first piston ring, and a non-metallic gasket.
  • The non-metallic gasket prevents combustion gases from escaping the combustion chamber.
  • The crankcase chamber operates without the need for oil.

Potential Applications

  • Automotive industry
  • Small engine applications (e.g., lawnmowers, generators)
  • Marine engines

Problems Solved

  • Reduced friction and wear due to the self-lubricating plastic material of the cylinder sleeve.
  • Improved sealing of the combustion chamber with the non-metallic gasket.
  • Elimination of oil in the crankcase chamber reduces maintenance and environmental impact.

Benefits

  • Increased engine efficiency and performance.
  • Extended engine lifespan due to reduced friction and wear.
  • Lower maintenance requirements and costs.
  • Reduced environmental impact by eliminating the need for oil in the crankcase chamber.


Original Abstract Submitted

an internal combustion engine includes an engine block, a piston, and a cylinder head. the engine block includes a cylinder block having a cylinder bore, a crankcase defining a crankcase chamber with a crankshaft positioned within the crankcase chamber, and a cylinder sleeve fabricated from a self-lubricating plastic material. the cylinder head is coupled to the cylinder block to form a combustion chamber. the piston includes a piston top adjacent the combustion chamber, a piston body including a wrist pin hole configured to receive a wrist pin, a first piston ring positioned on the piston body, and a non-metallic gasket positioned on the piston body closer to the combustion chamber than the first piston ring and structured to prevent combustion gases from escaping the combustion chamber. the crankcase chamber is oilless.
